Just recently traded in my 116613LB for the newer 41mm 126613LB, and Mr. Thanh Takuya was happy to oblige me in my efforts. He gave me a very fair trade-in value, and everything about the shipping and delivery went as smooth as could be, both with me shipping him MY previous watch, and him shipping me the new one. I wholeheartedly vouch for Thanh's business, he is a top-rate seller and I will certainly be looking forward to doing business with him in the future!
